REVERSIBLE MOLD-BOARD PLOW.

SPECIFICATION forming part of Letters Patent No. 424,400, dated March25, 1890. Application filed December 14, 1889. Serial No. 833,765. (Nomodel.)

To all whom it may concern: 5.

The lower end of the standard spring22, make the latch turn automatically where the diverging arms 1 and 2join each after it has been moved beyond the centers other is extendedforwardand backward for of the bearings. The hooks of the latch en- Ice50 a short distance to forma shoe Land furnished gage the edges of thebracket-arm 14 on one at the extreme ends with thebcaring-pintles sideor the other, according to the way the mold-board is turned. Foot-rests27 27 are formed back of the hooks, upon one of which the driver placeshis foot in order to disengage one hook from the arm 14, and after thelatch passes its center the other hook will automatically engage theother side of the arm 14. If the latch is changed before the mold-boardturns, the slanting edge 13 of the bracket-arm engaged by the hook,will, by its contact with the inclining lower edge of the hook, forcethe latter back until it locks the arm, where it will remain until againrocked and the mold-board is to be again reversed.

The mold-board is kept from turning over toofar by striking the arm 1 ofthe standard and the latch holds the mold-board against the standard,and a stop 28 on the rear of arm 2 prevents the latch from turning overbeyond that point.

The handles 30 30 of the plow are bolted or otherwise secured at theirlower ends to the arm 2 of the standard, and these handles are heldapart the required distance by the spacing-bars 31 and 32, to behereinafter referred. to.

0 indicates the beam of the plow. The rear end of this beam is fittedinto and secured to a casting 33, which forms a rear extension of thebeam. The extension bears upon the reach-bar at the forward and rearend. At the forward end it is pivoted by means of a bolt 34 and at therear end it is provided with a bolt 35, which extends into thetransverse elongated slot 36 in the rear end of the reachbar. The objectof this slotis to allowalimited lateral movement of the beam, and thebeam is swung by means of a lever 36, fulcrumed on the lower spacing-bar31. The lever is provided with a rounded elliptical slot or loop 38 atits lower end, which loosely receives a round projection 39 on the rearend of the extension and allows a free movement of the latter thereinwhen the lever is swung in either direction. The lever terminates in ahandle 40 at its outer end, by which it is manipulated, and a tooth 41on the back of the lever is adapted to enter one of the notches 42 42 onthe curved spacing-bar 32, by which it is locked in position. To swingthe beam this lever is simply swung to the right or left. The colter orj ointer 43 is also reversible, and to this end is secured 011 the endof the rod 44. Said rod extends obliquely through a bearing '45,.f0rmedfor it in the arm 1 of the standard and loosely through the transverseslot 46 in the casting or extension just back of the beam. An adjustableloop 47 for regulating the depth of cut of the colter is sleeved ontothe end of the rod and held rigidly thereto by means of a set-screw 48,and a flexible lever 49, pivoted on the bolt 35, extends back looselythrough this loop, and at its rear end is furnished with a handle 50,which extends nearly to the handles of the plow, where it may be easilygrasped by the plowman. The loop is provided in the middle with a lug5], overwhich the lever has to be thrown in order to reverse the colter.The lug prevents the colter from jolting over accidentally, as it wouldbe inclined to do if the lever were permitted to move freely to theother side of the loop. Again, the loop, by projecting forward a shortdistance, acts as a lever, so that when the hand-lever presses againstits outer orupper end it readily swings the rod and attached colter,whereas to merely swing the hand-leveracross the loop, if thelug weredispensed with, would not have this effect. A portion of the loop liesin the slot 46, and thus prevents the rod from moving endwise.

It is evident that slight changes might be resorted to-in the form andarrangement of the several parts described without departing from thespirit and scope of my invention, and hence I do not wish to limitmyself to the exact construction herein set forth but,

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination, with a standard, a rod having a bearing in saidstandard, and a colter secured to the rod, of a loop secured to the rod,and a hand-lever passing throughthe loop and adapted to swing the loop,rod, and colter, substantially as set forth.

2. The combination, with a standard, a reversible colter, and a rodhaving a bearing in the standard and to which the colter is secured, ofa loop secured to the end of the bolt, said loop having a lug projectinginto it, and a hand-lever pivoted on the standard and ex-- tendingthrough the loop, for the purpose described.

3. The combination, with a standard anda beam pivoted thereto, said beamhaving a slotted rear end, of a rod loosely mounted in. a bearing in thestandard and having a colter on one end and a loop on the other end, the

collar of which extends loosely in the slot in the upper spacing-bar,substantially as set forth.

5. The combination, with a standard having a transverse elongated slotin its upper rear portion, a beam pivoted on the standard, and a bolt inits rear end which extends loosely into the transverse slot to limit thelateral swings of the beam, of a reversible colter, the stem of whichpasses through the standard and beam, and levers for moving the colterand swinging the beam, substan tially as set forth.

6. The combination, with the standard and a reversible mold-board, of adouble-hooked spring-actuated latch for engaging the moldboard andlocking it on either side of the standard, and convex or roundedbearings on the latch adapted to impinge against the edge of thestandard and by their contact autonatically swing the latch when it haspassed its center, substantially as set. forth.

7. The combination, with a standard, of a reversible mold board pivotedthereto, a double-hooked latch for locking the moldboard, a pin or boltupon which the latch is pivoted, a spring on this pin, a nut forregulating the tension of the spring, and a sliding sleeve on the pininterposed between the spring and nut, substantially as set forth.

8. The combination, with a standard, of a mold-board having a socket onone side and a bracket-arm having a bearing in one end and inclines onthe edges, the socket and bearing adapted to receive pintles on the endsof the standard, and a pivoted springactuated double-hooked latch havinginclines on its lower edges and rounded or convex bearings 011 each sideof its center, substantially as set forth.

9. The combination, with a standard substantially triangular in form,comprising the arms 1 and 2 and the reach 3, and a beam pivoted on thestandard at the forward end and having a bolt in, the rear end which eX-tends into the transverse slot in the reachbar, of a reversiblemold-board, a spring-actuated double-hooked latch adapted to lock themold-board, a reversible col ter, and levers for swinging the colter andbeam and for locking them, substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing Witnesses.
